Available DSP Modules

Pitch Shifter

±12 semitones of pitch adjustment. Go higher for chipmunk/anime voices or lower for deep/demonic voices.

Formant Shifter

Change the timbre and resonance of your voice independently of pitch. Make a male voice sound female (or vice versa) while keeping natural pitch.

🏔️

Reverb

Add spatial depth with Room, Hall, Plate, or Cathedral reverb. Dial in decay time, damping, and wet/dry mix.

Equalizer

10-band graphic EQ. Boost presence at 3kHz for clarity, cut mud at 300Hz, or sculpt any frequency response you want.

Compressor

Even out your voice dynamics. Threshold, ratio, attack, release — full control for broadcast-quality consistency.

Noise Gate

Eliminate background noise between phrases. Adjustable threshold, attack, and release for clean, professional audio.

Voice Lab FAQ

What is the Voice Lab?

The Voice Lab is Echo's built-in effect designer. It lets you create custom voice effects by combining DSP (Digital Signal Processing) modules — pitch shifting, formant adjustment, reverb, EQ, compression, distortion, and more. Instead of using pre-made presets, you design your own unique voice from scratch. Think of it as a modular synthesizer for your voice.

What is the difference between Voice Lab and RVC voice models?

RVC voice models use AI to convert your voice into a specific person's voice — they change your voice identity. Voice Lab uses DSP effects to modify your voice's characteristics (pitch, tone, texture) without AI. You can use both together: apply an RVC model first for identity conversion, then use Voice Lab to fine-tune the output with EQ, compression, and reverb.

What effects are available in Voice Lab?
Currently available: Pitch Shifting (±12 semitones), Formant Shifting (change voice timbre without changing pitch), Reverb (room, hall, plate, cathedral presets), Noise Gate (eliminate background noise), Compressor (even out volume), EQ (10-band graphic equalizer), and Distortion (robotic/demonic textures). More modules are added regularly.
Can I save and share my custom voices?
Yes. Voice Lab creations are saved as presets that you can switch between instantly using hotkeys. Sharing is planned for a future update — you'll be able to export your preset as a file and share it with other Echo users.
Do Voice Lab effects add latency?
DSP effects are extremely lightweight and built for live use. Even with several effects stacked, the added delay should feel imperceptible for voice chat, streaming, and gaming.
